My research
I do research in cosmology, where I am mostly interested in extracting information about fundamental physics from large astronomical datasets on different wavelengths. In this sense, the two most interesting regimes in the evolution of the Universe are the mysterious accelerated expansion at late times, fueled by an unknown form of "Dark Energy", and the violent expansion of the Universe shortly after the Big Bang, since it provides a unique window into physical process at very high energies. I am heavily involved in two international collaborations trying to study these two epochs.
On the one hand, the will tackle the problem of Dark Energy by jointly studying the large-scale distribution of galaxies and the correlation in their shapes caused by the gravitational lensing effect. On the other hand, I am a member of the , an experiment that aims to observe the subtle imprint left by the gravitational waves emitted after the Big Bang on the polarization of its afterglow light (the so-called Cosmic Microwave Background).
Teaching
I currently teach two lecture courses:
- The Radiative Processes in Astrophysics component of the Astrophysics C1 module of the MPhys (4th-year) course. Lecture notes can be found .
- The Cosmology course within the MMathPhys programme. Lecture notes can be found .
